. However, this type of removal is not effective when the root cause stems from misprinted PCBs and pre-reflow solder paste issues. As a result, it is best to diagnose the cause of solder balls as early as possible, as these processes can negatively influence your PCB manufacturing and production

. An opposing school of thought was that voids act as crack arrestors, which improve solder joint life. The root cause of voids in BGA solder joints is well understood by the electronics industry with a number of papers published on the topic [1, 2, 3]. R
